How Can Inflation Contracts Discipline Central Bankers When Agents Are Learning?

Bulletin of Economic Research, EarlyView.
ABSTRACT This paper studies, in a new Keynesian model with a positive optimal output gap, how to design linear inflation contracts to shape the central bank's incentive structure when private expectations are based on adaptive learning. In this model, under rational expectations, inflation contracts could only partially deal with the time‐inconsistency

Building some symmetric Laguerre-Hahn functionals of class two at most through the sum of symmetric functionals as pseudofunctions with a Dirac measure at origin

International Journal of Mathematics and Mathematical Sciences, 2006
We show that if v is a symmetric regular Laguerre-Hahn linear form (functional), then the linear form u defined by u=−λx−2v+δ0 is also regular and symmetric Laguerre-Hahn linear form for every complex λ except for a discrete set of numbers depending ...

The Timing of Learning by Exporting: An Empirical Investigation on Ethiopian Large and Medium Manufacturing Firms

Review of Development Economics, EarlyView.
ABSTRACT This paper analyzes the link between export and total factor productivity using a large panel of Ethiopian large and medium manufacturing firms. Using a modified Olley and Pakes model with export for the prediction of total factor productivity and then matching and difference‐in‐difference techniques, evidence of both self‐selection and ...

Meta algebras and biorthogonal rational functions: The Hahn case

Forum of Mathematics, Sigma
The finite families of biorthogonal rational functions and orthogonal polynomials of Hahn type are interpreted algebraically in a unified way by considering the three-generated meta Hahn algebra and its finite-dimensional representations.

Exact analytical solutions of the Bloch equation for the hyperbolic‐secant and chirp pulses

Magnetic Resonance in Medicine, Volume 94, Issue 5, Page 2140-2149, November 2025.
Abstract Purpose To improve the accuracy and generality of analytical solutions of the Bloch equation for the hyperbolic‐secant (HS1) and chirp pulses in order to facilitate application to truncated and composite pulses and use in quantitative methods.

On 2-orthogonal polynomials of Laguerre type

International Journal of Mathematics and Mathematical Sciences, 1999
Let {Pn}n≥0 be a sequence of 2-orthogonal monic polynomials relative to linear functionals ω0 and ω1 (see Definition 1.1). Now, let {Qn}n≥0 be the sequence of polynomials defined by Qn:=(n+1)−1P′n+1,n≥0.

From Two‐Photon Grayscale Lithography to Scalable Replication: Enabling Complex Aspherical Micro‐Optics for Mass Production

Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.
This study presents the replication of micro‐optics fabricated by two‐photon polymerization grayscale lithography via electroplating and injection molding, enabling mass production without loss of precision. A diffractive aspherical micro‐lens array is fabricated and replicated, and its performance is compared before and after replication ...

Simplifying large spin bootstrap in Mellin space

Journal of High Energy Physics, 2018
We set up the conventional conformal bootstrap equations in Mellin space and analyse the anomalous dimensions and OPE coefficients of large spin double trace operators.

Body Size and Risk of Death During the 1918 Influenza Pandemic in Alaska

American Journal of Human Biology, Volume 37, Issue 10, October 2025.
ABSTRACT In the aftermath of the 2009 H1N1 influenza A pandemic, research revealed the relationship between body size and the severity of influenza outcomes. However, there is little data available on body size in historical populations; therefore, the relationship between body size and 1918 influenza pandemic outcomes is virtually unknown.

The Fractional Orthogonal Derivative

Mathematics, 2015
This paper builds on the notion of the so-called orthogonal derivative, where an n-th order derivative is approximated by an integral involving an orthogonal polynomial of degree n.
